CHAPTER 1: SERVICE PROCEDURES 

1.1 Functional Description 

The 45 Series fryers contain a welded steel (stainless or cold rolled) frypot that is directly heated by 

gas flames that are diffused evenly over its lower surface by ceramic targets. 

The flames originate from orifices in a U-shaped burner manifold positioned beneath the frypot. 

The orifice diameters differ for natural and propane gas as indicated in the table below (see Page 2-7 

for a complete list of available orifices). 

45 Series Orifice Sizes (0-1999 ft/609 m) 

Gas Inches Millimeters 

Natural 0.057 1.45 

Propane 0.034 0.86 

Gas flow to the manifold is regulated by an electromechanical gas valve. This series of fryers is 

equipped with a 24-volt gas valve and all models use a pilot ignition system. 

PILOT IGNITION SYSTEM 

The pilot ignition system is comprised of the pilot orifice, pilot hood, and a thermopile. The pilot 

serves two purposes. The first is to light the burner, the second is to heat the thermopile. In operation, 

the thermopile is in contact with the pilot flame and generates millivolts. The millivolt output 

passes through a normally closed high-limit switch and energizes the gas valve pilot coil, which in 

turn opens the pilot valve. If the pilot flame is extinguished, voltage is lost to the gas valve pilot coil 

and the pilot valve closes. A separate 24-volt circuit, activated by the fryer ON/OFF switch, provides 

voltage through the thermostat or controller to the gas valve main coil, which opens the main 

valve. The gas valve is constructed so that the main valve will not open if the pilot valve is not 

open. The pilot flame must be manually lit (either with a match or with an optional built-in piezo 

igniter) when the fryer is first placed into operation.

CONTROL OPTIONS 

45 Series fryers may be equipped with thermostat controllers, analog controllers, digital controllers, 

basket lift timers, or Computer Magic computers. 

In fryers equipped with thermostat controls, the fryer and melt cycle are turned on and off by means 

of rocker switches and the temperature is set by means of a knob connected directly to the frypotmounted 

thermostat. These units have no interface board. In this type of unit, when the melt cycle 

switch is placed in the ON position, the fryer stays in the melt cycle mode until the switch is manually 

placed in the OFF position, even if the frypot is at setpoint temperature. 

Fryers equipped with other types of controllers have an interface board located in the component 

shield behind the control panel. 

INTERFACE BOARDS 

The interface board provides the link between the controller/computer and the fryer’s individual 

components without requiring excessive wiring, and allows the controller to execute commands 

from one central point. When built, depending upon the configuration of the particular fryer, any 

one of three different boards may be used. Regardless of the particular board installed when the 

fryer was built, P/N 806-3548 is the universal replacement part.

Every board contains one heat relay (K3), and may contain two basket lift relays (K1 and K2). As 

shipped from the factory, fryers with bell crank basket lifts will have relays K1, K2, and K3. All 

other factory-original fryers will have boards with only relay K3. 

THERMOSTATS AND TEMPERATURE PROBES 

Different types of thermostats are used in 45 Series fryers, depending on the fryers’ configuration. 

Fryers equipped with Thermostat Controls have an adjustable controlling (operating) thermostat. 

The temperature at which the thermostat opens and closes is adjusted by physically changing the setting 

of the thermostat itself by means of an attached knob. When new, the Fenwal controlling thermostat 

used in 45 Series fryers is sensitive to one-degree changes in temperature. 

CAUTION 

Fenwal thermostats are used in a number of Frymaster products. The thermostat for 

the 45 Series is 4 inches long. Do not use 3-inch Fenwal thermostats in 45 Series 

fryers. 

Fryers equipped with all other type controls have a temperature probe. In these units, the probe 

resistance varies directly with the temperature. That is, as the temperature rises, so does resistance 

at a rate of approximately 2 ohms for every 1º (F or C). Circuitry in the controller monitors the probe 

resistance and controls burner firing when the resistance exceeds or falls below programmed 

temperatures (setpoints). The temperatures are programmed by means of a keypad on the face of the 

controller. 

All 45 Series fryers are equipped with a high-limit thermostat. In the event that the fryer fails to 

properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to 

the flash point. The high-limit thermostat acts as a normally closed power switch that opens when 

1-3

exposed to temperatures in the range of 425ºF to 450ºF (218ºC to 232ºC). The high-limit thermostat 

is the same for CE and Non-CE applications, but the terminals for attaching it to Robertshaw and 

Honeywell gas valves differ. When a replacement high-limit thermostat is ordered, make sure the 

kit appropriate for the valve in use is ordered. 

1.2 Accessing Fryers for Servicing 

DANGER 

Moving a fryer filled with cooking oil/shortening may cause spilling or splattering of 

the hot liquid. Follow the draining instructions in Chapter 4 of the 45 Series Gas 

Fryer Installation and Operation Manual before attempting to relocate a fryer for 

servicing. 

1. Shut off the gas supply to the unit. Unplug the power cord(s). Disconnect the unit from the gas 

supply. 

2. Remove any attached restraining devices. 

3. Relocate the fryer for service accessibility. 

4. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, 

and plug in the electrical cords. 

1.3 Checking the Burner Manifold Gas Pressure 

WARNING 

This task should be performed by qualified service personnel only. 

1. Ensure that the gas valve knob or button is in the OFF position. 

2. Remove the pressure tap plug from the end of the manifold (see illustration below for location) 

and connect a gas pressure-measuring device to the port. 

1-4 

Remove this plug and connect a gas 

pressure-measuring device to the port. 

3. Place the gas valve in the ON position then place the fryer power switch in the ON position. 

When the burner lights and continues to burn, compare the pressure reading to that for the corresponding 

gas in the tables on the following page.

5. Place the fryer power switch and the gas valve in the OFF position. Remove the fitting from the 

pressure tap hole and reinstall the plug. Place the gas valve in the ON position, and check for and 

eliminate any gas leaks. Place the gas valve in the OFF position. 

1.4 Adjusting the Pilot Flame 

1. On non-CE valves, remove the cap covering the pilot adjustment screw. On all valves, turn the 

pilot adjustment screw counterclockwise to increase the length of the flame or clockwise to decrease 

the length of the flame. Adjust the flame to a length of 1 to 1½ inches (25 to 38mm). 

To access the pilot adjustment screw on 

Non-CE valves, this cap must be removed.

1.5 Cleaning the Gas Valve Vent Tube 

1. Carefully unscrew the vent tube from the gas valve. NOTE: The vent tube may be straightened 

for ease in removal. 

2. Pass a piece of ordinary binding wire (.052 inch diameter) or equivalent through the tube to remove 

any obstruction. 

3. Remove the wire, then blow through the tube to ensure it is clear. 

4. Reinstall tube and bend it so that the opening is pointing downward. 

1.6 Adjusting Burner Ceramic Target Spacing and Alignment 

DANGER 

Drain the frypot or remove the handle from the drain valve before proceeding further. 

Proper spacing of the top edge of the burner ceramic targets is ¾ inch (13 mm) from the frypot side. 

To adjust target spacing, bend the brackets to which they are attached away or toward the frypot to 

the proper distance. (A length of board of the proper thickness is useful as a gauge to verify spacing 

and alignment.) 

1.7 Calibrating the Thermostat Control 

NOTE: The fryer control panel must be hinged down from the control panel mounting frame to perform 

thermostat calibration. In order to hinge the control panel down, the thermostat knob must be 

removed from its shaft. It is secured with a setscrew located opposite the index mark on the knob. 

1. Fill the frypot to the lower OIL-LEVEL line with cooking oil/shortening. If solid shortening is 

used, it must be pre-melted before starting the calibration procedure. 

2. Ensure the fryer ON/OFF Switch is in the OFF position, then light the pilot. (Refer to Chapter 3 

of the 45 Series Gas Fryer Installation and Operation Manual for detailed lighting instructions.) 

3. Insert a good grade thermometer or pyrometer into the frypot so that it touches the thermostat 

guard. 

4. Loosen the setscrew and stop screw securing the thermostat 

shaft extension to the flexible shaft. Remove 

the extension to expose the slot in the end of the flexible 

shaft. 

5. Place the fryer ON/OFF switch in the ON position. 

NOTE: If the burner does not light at this time, it 

does not mean the thermostat is defective! 

Use a small flat-tipped screwdriver to slowly turn the flexible shaft counterclockwise until the 

burner lights. Turning the shaft counterclockwise causes the burner to light and clockwise 

causes it to shut off.

Setscrew

6. When the cooking oil/shortening temperature reaches 325ºF (162ºC), turn the flexible shaft 

slowly clockwise until the burner shuts off. 

7. Allow the fryer to sit for a few minutes, then slowly turn the flexible shaft counterclockwise until 

the burner lights. 

8. Repeat steps 6 and 7 at least three times to ensure an accurate setting is obtained. The Thermostat 

Control is considered to be properly calibrated when the burner lights as the cooking 

oil/shortening cools to 325ºF (162ºC)—not when the burner shuts off as the temperature rises. 

9. Once the calibration point of 325ºF (162ºC) is determined, allow the burner to cycle on and off at 

least 3 times to be sure it will light at the calibrated temperature. 

10. After the calibration is complete, place the fryer power switch in the OFF position and disconnect 

the fryer from the electrical supply. 

11. Carefully replace the thermostat shaft extension, ensuring that the stop screw is pointed straight 

up. Tighten the stop screw and locking nut and the setscrew, being careful not to rotate the flexible 

shaft. 

CAUTION 

The thermostat flexible shaft must not be rotated while installing the thermostat 

shaft extension! 

When handling the thermostat, do not rotate the shaft more than two turns in either 

direction. Doing so will cause damage to the thermostat. 

12. Close the fryer control panel and replace the screws the upper corners. 

13. Reinstall the thermostat knob with its pointer aligned with the 325ºF (162ºC) index mark on the 

temperature dial. 

14. Reconnect the fryer to the electrical supply.

1.9 Troubleshooting and Problem Isolation 

Because it is not feasible to attempt to include in this manual every conceivable problem or trouble 

condition that might be encountered, this section is intended to provide technicians with a general 

knowledge of the broad problem categories associated with this equipment, and the probable causes 

of each. With this knowledge, the technician should be able to isolate and correct any problem encountered. 

1-15

Problems you are likely to encounter can be grouped into seven broad categories: 

1. Ignition failures 

2. Improper burner functioning 

3. Improper temperature control 

4. Computer-related problems 

1-16 

5. Filtration problems 

6. Leakage problems 

7. Basket lift malfunctions 

The probable causes of each category are discussed in the following sections. A series of Troubleshooting 

Guides (decision trees) is also included at the end of the chapter to assist in identifying 

some of the more common problems. 

1.9.1 Ignition Failures 

Ignition failures occur when the 24VAC power supply to the gas valve is interrupted, when the gas 

supply is interrupted, or when the pilot flame is extinguished. 

Solid-state controllers indicate ignition failure by illuminating the heat light and trouble light simultaneously. 

All other controllers give no specific indication of an ignition failure. 

There are three primary reasons for ignition failure, listed in order of probability: 

1. Problems related to the gas and/or electrical power supplies. 

2. Problems related to the electronic circuits. 

3. Problems related to the gas valve. 

PROBLEMS RELATED TO THE GAS AND/OR ELECTRICAL POWER SUPPLIES 

The main indicators of this are that an entire battery of fryers fails to light and/or there are no indicator 

lights illuminated on the fryer experiencing ignition failure. Verify that the quick disconnect 

hose is properly connected, the fryer is plugged in, the main gas supply valve is open, and the circuit 

breaker for the fryer electrical supply is not tripped. 

PROBLEMS RELATED TO THE ELECTRONIC CIRCUITS 

If gas and electrical power are being supplied to the fryer, the next most likely cause of ignition failure 

is a problem in the 24 VAC circuit of the pilot system. If the fryer is equipped with a Filter 

Magic II filtration system, first verify that the drain valve is fully closed. (The valve is attached to a 

microswitch that must be closed for power to reach the gas valve. Often, although the valve handle 

appears to be in the closed position, the microswitch is still open.) If the valve is fully closed, or the 

fryer does not have a filtration system, refer to the troubleshooting guides TROUBLESHOOTING THE 

24 VAC CIRCUIT. 

PROBLEMS RELATED TO THE GAS VALVE 

If the problem is not in the 24 VAC circuit of the pilot system, it is most likely in the gas valve itself, 

but before replacing the gas valve refer to TROUBLESHOOTING THE GAS VALVE on page 1–32.

1.9.2 Improper Burner Functioning 

With problems in this category, the burner ignites but exhibits abnormal characteristics such as 

“popping,” incomplete lighting of the burner, fluctuating flame intensity, and flames “rolling” out of 

the fryer. 

“Popping” indicates delayed ignition. In this condition, the main gas valve is opening but the burner 

is not immediately lighting. When ignition does take place, the excess gas “explodes” into flame, 

rather than smoothly igniting. 

The primary causes of popping are: 

• Incorrect or fluctuating gas pressure 

• Misdirected or weak pilot flame 

• Burner deflector targets out of alignment or missing 

• Clogged burner orifices 

• Inadequate make-up air 

• Clogged vent tube, causing incorrect gas pressure 

If popping occurs only during peak operating hours, the problem may be incorrect or fluctuating gas 

pressure. Verify that the incoming gas pressure (pressure to the gas valve) is in accordance with the 

appropriate CE or Non-CE Standard found in the table below, and that the pressure remains constant 

throughout all hours of usage. Refer to Checking the Burner Manifold Pressure (Section 1.3) for 

the procedure to checking the pressure of gas supplied to the burner.

Orifice Diameter Pressure Consumption 

If popping is consistent during all hours of operation, verify that the pilot is properly positioned 

above the burner orifice and that the pilot pressure is correct. Correct pilot pressure is indicated by a 

flame 1 to 1½” (25 to38 mm) long. Refer to Section 1.6 for the pilot flame adjustment procedure. 

Clogged burner orifices, especially those near the pilot, are also likely causes of delayed ignition. 

Clogged orifices are indicated by no flame, flames that are orange-colored, and flames that shoot out 

at an angle from the rest. 

Another cause of popping is an insufficient air supply or drafts that are blowing the pilot flame away 

from the burner. Check for “negative pressure” conditions in the kitchen area. If air is flowing into 

the kitchen area, this indicates that more air is being exhausted than is being replenished and the 

burners may be starved for air.

If the fryer’s gas and air supplies are okay, the problem most likely is with one of the electrical components. 

Examine the controller for signs of melting/distortion and/or discoloration due to excessive 

heat buildup in the fryer. (This condition usually indicates improper flue performance.). A discolored 

or distorted controller is automatically suspect and should be replaced. However, unless the 

condition causing excessive heat in the fryer is corrected, the problem is likely to recur. 

The burner lighting on one side only may be caused by a missing or misaligned rear deflector target 

or improper burner manifold pressure. Clogged burner orifices are usually the cause of gaps in 

burner firing. 

Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas pressure, 

but may also be the result of variations in the kitchen atmosphere. Verify incoming gas pressure 

in the same way as for “popping,” discussed in the preceding paragraphs. Variations in the 

kitchen atmosphere are usually caused by air conditioning and/or ventilation units starting and stopping 

during the day. As they start and stop, the pressure in the kitchen may change from positive or 

neutral to negative, or vice versa. They may also cause changes in airflow patterns that may affect 

flame intensity. 

Flames “rolling” out of the fryer are usually an indication of negative pressure in the kitchen. Air 

is being sucked out of the fryer enclosure and the flames are literally following the air. If negative 

pressure is not the cause, check for high burner manifold gas pressure in accordance with the procedures 

in Section 1.3, Checking the Burner Manifold Pressure. An obstructed flue, which prevents 

the fryer from properly exhausting, may also be the cause. 

An excessively noisy burner, especially with flames visible above the flue opening, may indicate 

that the burner gas pressure is too high, or it may simply be that the gas valve vent tube is blocked. 

If the gas pressure is correct and the vent tube in unobstructed, the gas valve regulator is probably 

defective. 

Occasionally a burner may apparently be operating correctly; nevertheless, the fryer has a slow recovery 

rate. (The recovery rate is the length of time required for the fryer to increase the oil temperature 

from 250ºF to 300ºF (121ºC to 149ºC)). The primary causes of this are low burner manifold 

pressure and/or misaligned or missing deflector targets. If both of these causes are ruled out, 

the probable cause is a gas valve regulator that is out of adjustment. Refer to Checking the Burner 

Manifold Pressure in Section 1.3. 

1.9.3 Improper Temperature Control 

Temperature control, including the melt cycle, is a function of several interrelated components, each 

of which must operate correctly. The principle component is the thermostat (in thermostat control 

units) or the temperature probe (in fryers equipped with other types of controllers). Depending 

upon the specific configuration of the fryer, other components may include the interface board and 

the controller. 

Improper temperature control problems can be categorized into melt cycle problems and failure to 

control at setpoint problems. 

1-18

MELT CYCLE PROBLEMS 

In fryers equipped with thermostat controls, the melt cycle is controlled by a mechanical timer. 

There are three components that may fail: the melt cycle timer itself, the melt cycle timer microswitch, 

or the control panel melt cycle ON/OFF switch. In all cases, the defective component 

must be replaced. 

In fryers equipped with other types of controllers, the problem may be with the controller itself, the 

temperature probe, or a malfunctioning heat relay on the interface board. 

For problem isolation techniques, refer to the troubleshooting guides TROUBLESHOOTING THE 

THERMOSTAT and TROUBLESHOOTING THE TEMPERATURE PROBE. 

FAILURE TO CONTROL AT SETPOINT 

In fryers equipped with thermostat controls, the problem will be with the thermostat itself. Possible 

causes are that the thermostat is out of calibration, the knob or flexible shaft is loose on the thermostat 

shaft, a thermostat wire is disconnected or broken, or the thermostat is defective. Refer to Section 

1.7 for instructions on calibrating the thermostat. 

In fryers equipped with other types of controls, the problem may be with the temperature probe, the 

interface board, or the controller. Refer to the troubleshooting guide TROUBLESHOOTING THE 

TEMPERATURE PROBE for problem isolation techniques. 

1.9.4 Computer-Related Problems 

COMPUTER MAGIC FEATURES 

SENSITIVITY OR “STRETCH AND SHRINK TIME” 

Sensitivity or stretch time is a programmable feature, patented by Frymaster that increases or 

decreases the cook time countdown based on variations in the oil temperature from the set point. 

The sensitivity for each product button has ten settings (0 through 9). A zero sensitivity setting will 

disable the feature (no change in cooking time), while a nine will provide the highest sensitivity or 

most change. The correct sensitivity for any product is based on the product, its density, the set 

point temperature, and the customer’s own requirements. 

RECOVERY TIME 

Recovery time or rate of rise is a method of measuring a fryer’s performance. Put simply, it is the 

time required for the fryer to increase the oil temperature from 250ºF to 300ºF (121ºC to 149ºC). 

This range is used as a standard since ambient kitchen temperatures can effect the test if lower 

ranges are used. 

The Computer Magic performs the recovery test each day as the fryer warms up. An operator can 

view the results of the test any time the fryer is above the 325ºF (163ºC) point by pressing the 

button and entering the code 1652. The test results will be displayed in the computer’s LED panel in 

minutes and seconds. The acceptable recovery time for 45 Series fryers is 2 minutes and 25 seconds. 

1-19

COMMON COMPUTER COMPLAINTS 

Most problems concerning computers have to do with programming them. There are four common 

complaints. The complaints, their causes, and corrective actions are: 

1. Fryer constantly displays “HI.” 

Cause: Setpoint incorrect or missing. 

Corrective Action: Press 1650, enter the correct setpoint using keypad, then press to lock 

in the setpoint. 

2. Temperature is displayed in Celsius. 

Cause: Computer is programmed to display in Celsius. 

Corrective Action: Press 1658. 

3. Temperature is constantly displayed. 

Cause: Computer is programmed for constant temperature display. 

Corrective Action: Press 165L. 

4. Computer times down too slowly or too quickly. 

Cause: Computer is compensating for oil temperature via the sensitivity setting. 

Corrective Action: Reprogram sensitivity setting for each product in accordance with programming 

instructions in Chapter 3 of the 45 Series Gas Fryer Installation and Operation Manual. 

1.9.5 Filtration Problems 

The majority of filtration problems arise from operator error. One of the most common errors is 

placing the filter paper on the bottom of the filter pan rather than over the filter screen. 

Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation 

of the filter paper, including that the correct size is being used. While you are checking the filter 

paper, verify that the O-rings on the bottom of the filter pan and on the male disconnect (at inside 

rear of filter cabinet) are present and in good condition. Missing or worn O-rings will allow the 

pump to suck air and decrease its efficiency. 

If the pump motor overheats, its thermal overload will trip and the motor will not start until it is reset. 

If the pump motor does not start, press the red reset switch located on the end of the motor nearest 

the operator. If the pump then starts, something caused the motor to overheat. It may be just that 

several frypots were being filtered one after the other and the pump got hot. Letting the pump cool 

down for at least a half-hour is all that is required in this case. More often, the pump overheated for 

one of the following reasons: 

• Shortening was solidified in the pan or filter lines. 

1-20

• The operator attempted to filter oil or shortening that was not heated. Cold oil and shortening 

are thicker and cause the pump motor to work harder and overheat. 

If the motor tries to run but the pump does not, there is a blockage in the pump. Incorrectly sized or 

installed paper will allow food particles and sediment to pass through the filter pan and into the 

pump. When sediment enters the pump, the gears can bind up causing the motor to overload, again 

tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with the 

same result. 

A pump seized by debris or hard shortening can 

usually be freed by manually moving the gears 

with a screwdriver or other instrument. 

1. Disconnect power to the filter system. 

2. Remove the input plumbing from the pump. 

3. Use a screwdriver to manually turn the gears. 

• Turning the pump gears backwards will 

release a hard particle and allow its removal. 

• Turning the pump gears forward will 

push softer objects and solid shortening 

through the pump and allow free movement 

of the gears.

Incorrectly sized or installed paper will also allow food particles and sediment to pass through and 

clog the suction tube on the bottom of the filter carriage. Particles large enough to block the suction 

tube may indicate that the crumb tray is not being used. 

Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip 

on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will 

not melt or prevent solidification of shortening in the pan. 

Blockage removal can be accomplished by forcing the item out with an auger or drain snake. Compressed 

air or other pressurized gases should not be used to force out the blockage. 

Possible problems with the Power Shower include clogged openings, shortening solidified in the 

tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing missing 

plugs and missing or worn O-rings will correct these problems. 

The electronics of the Filter Magic II are simple and straightforward. Microswitches, attached to the 

drain valve handles of each vat and wired in parallel, provide the 24 VAC needed to activate the 

pump relay coil when the handles are moved to the ON position. The activated coil pulls in the 

pump motor switch, supplying power to the motor.

The suction tube heater and flexible hose heater are wired directly into the 24VAC source. They 

remain energized as long as the unit is plugged in.

Filter Magic Simplified Wiring Diagram 

Leakage of the frypot almost always will be due to improperly sealed high limit switches, thermostats/temperature 

probes, and drain fittings. When installed or replaced, each of these components 

must be sealed with Loctite PST56765 sealant or equivalent to prevent leakage. In very rare cases, a 

leak may develop along one of the welded edges of the frypot. When this occurs, the frypot must be 

replaced. 

If the sides and/or ends of the frypot are coated with oil/shortening, the most likely cause is spillage 

over the top of the frypot rather than leakage. 

The clamps, which hold the drain tube sections together, may loosen over time as the tubes expand 

and contract with heating and cooling during use. If the section of drain tube connected to the drain 

valve is removed for whatever reason, make sure that its grommet is in good condition and properly 

fitted around the nipple of the drain when it is reinstalled. Also, check to insure that the drain tube 

runs downward from the drain along its whole length and has no low points where oil or shortening 

may accumulate. 

1.9.7 Basket Lift Malfunctions 

45 Series fryers may optionally be equipped with automatic basket lifts to ensure uniform cooking 

times. The lifts may be configured for manual control or for control via a Basket Lift Timer or 

Computer Magic computer. Basket lifts will always come in pairs, although each operates independently. 

In units configured for manual (push-button) controls, a mechanical or electrical timer controls voltage 

to the system. A rotary knob is turned to set the cook time, and pressing the button in the middle 

of the knob activates the motor. 

In units with Computer Magic or Basket Lift Timers, timing circuitry in the controller initiates and 

stops basket lift operation depending upon the variables programmed by the operator. When the 

M

product button is pressed, the timing circuitry activates a coil in the basket lift relay to supply power 

to the motor. 

There are two types of basket lifts: the “bell crank” design, and the “modular” design 

A bell crank basket lift consists of a cam and 

bell crank that are connected to the basket lift 

arm by a flat metal link. The cam is attached 

to a drive motor. The motor rotates the cam, 

thus raising or lowering the lift arm linked to 

the bell crank. A roller-activated microswitch 

is used to limit travel. When the push-button 

in the manual timer or the product button for 

computers is pushed, the motor circuit is completed 

and the motor runs, lowering the basket. 

When the roller in the microswitch 

makes or loses contact with the cam, the 

switch is reversed and power to the motor is 

cut. At the end of the specified cooking time, 

the timer/controller reverses its switch position 

so that the motor circuit is again complete. 

The motor runs, raising the basket, until 

contact with the cam is again made or lost.

When the timer button is pushed, the NO circuit in the timer is closed, 

supplying voltage through the microswitch to the motor. The bell 

crank/cam rotates until switch postition in the microswitch is reversed, 

stopping the motor with the basket in the down position. When the timer 

reaches zero, the the switch in the timer reverts to the NC position. This 

supplies power to the motor via the microswitch. Once again, rotation 

of the bell crank/cam eventually causes the microswitch to reverse 

itself, stopping the motor with the basket in the up position.

A modular basket lift consists of a toothed rod to which the basket lift arm is attached, a reversibledrive 

gear motor, and a pair of roller activated microswitches. The gear motor engages the teeth in 

the rod, moving it up or down depending upon the direction of rotation of the motor. Microswitches 

at the upper and lower limits of movement stop the motor when the basket is in the full up or full 

down position and also reverse the direction of current flow thus reversing the motor direction. 

When the manually set or programmed cooking time has elapsed, current is again supplied to the 

basket lift and the basket is raised. 

When the timer times-out, power is supplied to the opposite pole of the motor through the upper 

microswitch. The motor drives the rod upward until it loses contact with the upper microswitch, 

cutting power to the motor and stopping the lift. 

In units configured for Basket Lift Timer Controllers or Computer Magic computers, the process is 

almost identical. The difference is that the push button mechanical timer is replaced with timing circuitry 

in the computer or controller. The specific cook times (and other settings) are programmed 

into the computer or controller by the operator. When the product button is pressed, the timing circuitry 

activates a coil in the basket lift relay to supply power to the lower microswitch. As with the 

manually controlled units, the microswitches stop the motor at the lift’s upper and lower travel limits 

and reverse the direction of current flow thus reversing the motor direction. 

Problems with the basket lift system can be grouped into three categories: 

• Binding/jamming problems 

• Motor and gear problems 

• Electronics problems

activated, causing the basket lift to be raised, reclosing the lower 

microswitch. When the basket lift rod clears the upper 

micorswitch, allowing it to reopen, power to the circuit is cut and 

the motor stops. Pushing the timer button again restarts the 

cycle.

lowered, closing the normally open upper microswitch. When the 

lower normally closed microswitch is opened by the downward 

moving basket lift rod, power to the motor is cut. When the 

computer/controller times-out, the current to the relay coil is cut, 

allowing the upper circuit to be activated. This causes the basket 

lift to be raised, reclosing the lower microswitch. When the basket 

lift rod clears the upper micorswitch, allowing it to reopen, power 

to the circuit is cut and the motor stops. Pushing the product 

button again restarts the cycle.

BINDING/JAMMING PROBLEMS 

230/240/250V Modular Basket Lift Assembly 

Noisy, jerky or erratic movement of the lifts is usually due to lack of lubrication of the rods and their 

bushings. Apply a light coat of Lubriplate or similar lightweight white grease to the rod and bushings 

to correct the problem. 

Another possible cause of binding, in the case of modular basket lifts, is the improper positioning of 

the motor, which prevents the gear from correctly engaging the teeth in the rod. To correct the 

problem, loosen the screws that hold the motor in place and move it forward or backward until the 

rod has just enough slack to be rotated slightly. 

MOTOR AND GEAR PROBLEMS 

In modular basket lift units, the most likely problem to be encountered in this category is erratic motion 

of the lift due to a worn drive gear. Failure to keep the lift rod and bushings properly lubricated 

will cause unnecessary wear of the gear. The problem is corrected by replacing the worn gear. 

If the lift cycles correctly but fails to remain in the up position (i.e., goes up, but then slowly settles 

back down into the frypot), the problem is a failed motor brake. A failed motor brake cannot be repaired 

and requires replacement of the motor itself. 

If power is reaching the motor but the motor fails to run, the motor is burned out and must be replaced.

ELECTRONICS PROBLEMS 

This category encompasses problems with the relays, microswitches, capacitors, resistors, interface 

board, wiring, and controls. Troubleshooting the electronics of both bell crank and modular basket 

lifts is simply a process of verifying current flow through the individual components up to and including 

the motor. Using a multimeter set to the 250 VAC range, check the connections on both 

sides of the component for the presence of 120 VAC. 

The simplified wiring diagrams that follow identify the components and wiring connection points.

1.9.8 Interpretation of Digital Controller Lights 

Power light on, heat light cycling, trouble light off, and melt light on: 

• If fryer oil temperature is below 180ºF (82ºC), the lights indicate the unit is operating normally. 

• If the oil temperature is above 180ºF (82ºC) and the heat light continues to cycle as if in the 

melt cycle, this may indicate a defective probe circuit or low incoming 12VAC to the controller. 

Power light on, heat light on, trouble light off, and melt light off: 

• If the fryer oil temperature is above 180ºF (82ºC) and below the setpoint temperature, the 

lights indicate the unit is operating properly. 

• If the oil temperature is above the temperature set on the control knob and the heat light remains 

lit, this may indicate a defective probe circuit. 

Power light on, heat light off, trouble light on, and melt light off: 

• If the fryer oil temperature is below 410ºF (210ºC), the lights indicate one of the following: 

a. The probe circuit is defective, or 

b. There is a connection problem on pins 2 or 10 on the 15-pin wiring harness. 

• If the fryer oil temperature is above 410ºF (210ºC), the lights indicate a run-away heating circuit.
